Abstract: PROBLEM TO BE SOLVED: To improve extraction accuracy of an effective channel width in a drain current method. SOLUTION: A transistor having the wide channel width as a reference and a transistor having the narrow channel width as the extracting object for the effective channel width are prepared (step ST1.1). From the mask-channel width and the characteristic curve of the conductance plane between a source and a drain, the imaginary point where the change of the conductance between the source and the drain is estimated as approximately 0 even if gate over-drive is finely changed, is extracted. The value of the function F, which is determined by the difference between the rate of the conductance change in the coordinates of the imaginary point and the product obtained by multiplying the conductance per unit width by the changing rate of the mask-channel width, is computed. (step ST1.6). From the shifting amount δ, where the standard deviation of the function F obtained in a step ST 1.7 becomes minimum, the true threshold of the transistor having the narrow channel width is determined (step ST 1.10).

Filed: 1983-12-19
Abstract: PURPOSE:To facilitate the work and assembly of a lens barrel which holds plural lenses by using a casing which has >=3 axial slanting grooves in the barrel internal surface and lens holding pieces which slide while engaging the grooves. CONSTITUTION:The slanting grooves 9 are formed in the cylindrical internal surface of the casing 20 at least three positions, and the projection parts 16 of the lens holding pieces 13 engage with the grooves 9. When they are assembled, the lens holding pieces 13 are inserted into the casing 20 by the thickness of one lens and then the lens 17 is inserted in the diameter direction. When the lens holding pieces 13 are inserted along the grooves 9 in the casing 20 as shown by an arrow, the grooves 9 slant, so the lens 17 is fixed tightly. Further, a lens 18 is put in and inserted in an (x) direction until the front end of a lens holding frame abuts on the annular projection part 11 of the casing 20. Then, an elastic ring 10 is fitted in the annular groove part 12 of the casing 20 and the lens holding pieces 13 are fixed in an assembled state.

Abstract: PURPOSE:To improve test ability by adding the 2nd capacitor and superposing a residual voltage on the residual voltage of the 1st capacitor. CONSTITUTION:A device 3 to be tested and auxiliary breakers 6 and 7 are closed and an auxiliary breaker 8 is opened. Then, an electric generator 1 excites a power transformer 2, whose secondary voltage is adjusted to a test voltage E to open the breaker 6 with its peak value, so that the voltage E remains in the 2nd capacitor 5. Then, when the device 3 to be tested and breaker 7 are opened with forecasted cutoff phase of the device 3 to be tested, a voltage E having the opposite polarity of the capacitor 5 remains in the 1st capacitor 4. Then, when the breaker 8 is closed, the load-side voltage V2 of the device 3 to be tested is the residual voltage which is the sum 2R of the residual voltages of the capacitors 4 and 5. Therefore, the voltage between the electrodes of the device 3 to be tested is V1-V2 or 3E, thereby obtaining a test voltage which is about 1.5 time the conventional test voltage.

Title: Signal processor
Inventor: KAWASAKI MOTOAKI
IPC: H04B1/62
Filed: 1987-09-22
Abstract: PURPOSE:To reduce the influence of a noise component in an input signal and to enable accurate amplification based upon specific amplification characteristics by providing plural compressing means which have mutually different compression characteristics. CONSTITUTION:When compressing circuits 23a and 23b which have mutually different compression characteristics are used, high-frequency component signals outputted by the compressing circuits 23a and 23b after nonlinear processing differ in level because of the different compression characteristics even if high- frequency component signals supplied from high-pass filters HPF22a and HPF22b contain similar random noises unless the levels of the random noises are large. Further, those signals are multiplied by a coefficient K/2 through coefficient multiplying circuits 25a and 25b and added by an adder 21 to an input brightness signal. Consequently, the high-frequency component signals after the nonlinear processing and coefficient multiplication processing by the compressing circuits 23a and 23b owing to the random noises become low in level and accurate nonlinear emphasis is performed.

Abstract: PURPOSE:To improve performance, and downsize a device by arranging portal- shape piping having top part piping higher than a water level of a sealed tank between the sealed tank and a garbage crusher, and arranging a check valve of a garbage crusher side vertical pipe. CONSTITUTION:When an underwater pump 2 is operated, waste water in a tank 1 enters a nozzle 10 through circulating piping 9, and garbage and the waste water are sucked from an inflow port 6. Next, a ball type check valve 4 of portal-shape piping 3 is opened, and the garbage and the waste water are sucked from a garbage crusher 5, and are delivered into the tank 1 from a pump 2, and pressure in the tank 1 is increased, and they are discharged through external piping 12. Next, when the pump 2 is stopped, though the waste water in the tank 1 flows backward through the piping 9 or the like, since the piping 3 is high, the waste water does not go over this. The valve 4 cuts off an offensive smell from returning to a sink by closing pipe inside air pressure. After the waste water or the like is sucked, fresh water is sucked in the piping 3, and it is cleaned. Thereby, a counteflow of the waste water and the offensive smell can be prevented, and a device can be also made compact.

Abstract: PURPOSE:To improve shift accuracy without using an error correction mechanism by discharging heat in the opposite direction to a table with an air blowing means and wholly absorbing the force in the different vector from the shift direction of the table within the thrust generated by a linear motor with a drive member. CONSTITUTION:When a linear motor 7 is energized, the generated thrust is transmitted to a drive member 2 connected to a table 1, and the table 1 is moved in a straight line on guide rails 6, 6 together with the drive member 2.
